BRE A line is drawn through (-7, 11) and (8, -9). The equation
y-11=(x +
+ 7) is written to represent the line. Which
equations also represent the line? Check all that apply.
1. For parentheses
Distribute
y-11 =
(x+7)
O y = -4x+
=
2. If necessary
Combine Terms
O 3y = -4x + 40
4x + y = 21
4x + 3y = 5
0 - 4x + 3y = 17
3. Apply properties
Add Subtract

Intro

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2
